On the label it suggests you use it on a daily basis and in an unexpected amount (6 scoops for an intense workout?!- I only use two). If you're going to follow their recommendations, buy the larger amount. It does give me energy though! And the fruit punch tastes great. I wish it came with a shaker cup as a bonus instead of a pen.

This flavour is the best that I have tried of the range, so far. Not especially keen on Grape & have yet to try Orange.
Are stand alone EAA's necessary? Probably not, but this does supply a " halfway " solution to a more healthier pre-training drink, in my view.
As for being necessary, read Suppversity.com where studies show that a cheap whey with the addition of some casein is really all that any of us need throughout the day. Forget the additional EAA's / BCAA's / Glutamine - none are necessary.
Apparently FACT!
